What I described is an encrypted filesystem over a plain-and-simple LV,
and the procedure you could follow to take snapshots from this LV,
which holds an encrypted filesystem, and make filesystem-level backups
(such as those made with tar, cpio, rsync and others).

At least in Debian, "losetup" comes with the "mount" package.

Then maybe we are talking about different things here. I used an
encrypted filesystem over an unencrypted LV but, as loop-aes needs the
loop device to operate, I need to loop-mount the encrypted filesystem for
the system to be able to on-the-fly decrypt its contents.

Maybe I am confused, because I don't fully understand what you mean by
"running LVM ontop of a encrypted loopback device".
